Abstract

Un rotor à disques à ventilation radiale est réalisé de telle manière que le diamètre intérieur des disques de forme annulaire 8 est plus grand que les diamètres extérieurs du moyeu 1, 2 et que le moyeu 1, 2 n'est relié aux disques annulaires 8 qui portent la jante du rotor 9 que par des pales obliques 4, 5. Les pales obliques 4, 5 jouent le rôle d'éléments porteurs, d'éléments de guidage et d'éléments de ventilation. Les pales obliques 4, 5 se composent judicieusement d'une partie intérieure 4 et d'une partie extérieure 5, les points de jonction 6, avantageusement réalisés sous la forme de jonctions soudées, se trouvant dans les zones où les sollicitations mécaniques sont minimales, et où ces points de jonction sont aussi bien accessibles. Le rotor à disque convient en particulier pour de grandes machines.A rotor with radially ventilated discs is made in such a way that the inside diameter of the annular discs 8 is larger than the outside diameters of the hub 1, 2 and that the hub 1, 2 is not connected to the annular discs 8 which carry the rim of the rotor 9 only by oblique blades 4, 5. The oblique blades 4, 5 play the role of load-bearing elements, guide elements and ventilation elements. The oblique blades 4, 5 are judiciously composed of an internal part 4 and an external part 5, the junction points 6, advantageously produced in the form of welded junctions, being in the zones where the mechanical stresses are minimal, and where these junction points are accessible as well. The disc rotor is particularly suitable for large machines.
